-- [pysnmp](https://github.com/etingof/pysnmp) - This is a pure-Python, open source and free implementation of v1/v2c/v3 SNMP engine distributed under 2-clause BSD license.
-  - This project has been abandoned [due to the death of the sole maintainer](https://github.com/etingof/pysnmp/issues/427).
-  - Some forks have been created to continue the project and the ecosystem around it. See [here](https://github.com/etingof/pysnmp/issues/429).
-  - The leading fork seems to be [lextudio/pysnmp](https://github.com/lextudio/pysnmp). ![GitHub last commit](https://img.shields.io/github/last-commit/lextudio/pysnmp)
-  - There is also a [community fork](https://github.com/pysnmp/pysnmp) under active development, but it is not clear if that project is commited to maintaining all the associated repos, documentation, and websites. ![GitHub last commit](https://img.shields.io/github/last-commit/pysnmp/pysnmp)

 - [gufo_snmp](https://github.com/gufolabs/gufo_snmp) - The accelerated Python SNMP client library supporting both async and synchronous mode. It consists of a clean Python API for high-efficient BER parser and socket IO, implemented in the Rust language with PyO3 wrapper. Seems to be a bit early in the project's lifecycle, but it is easy to use and ___extremely___ fast, especially when querying many devices. ![GitHub last commit](https://img.shields.io/github/last-commit/gufolabs/gufo_snmp)
 - [net-snmp Python bindings](http://www.net-snmp.org/wiki/index.php/Python_Bindings) - Net-SNMP 5.4 and later contains Python bindings in the "python" sub-directory, though, they are not built by default. ![GitHub last commit](https://img.shields.io/github/last-commit/net-snmp/net-snmp)
 - [easysnmp](https://github.com/easysnmp/easysnmp) - A fork of [net-snmp Python bindings](http://www.net-snmp.org/wiki/index.php/Python_Bindings) that attempts to bring a more Pythonic interface to the library. ![GitHub last commit](https://img.shields.io/github/last-commit/easysnmp/easysnmp)
